Abstract

Los datos son transferidos en un sistema de comunicación inalámbrica, como ser un sistema de comunicación inalámbrica espectro disperso. Los datos son codificados para producir una pluralidad de corriente de datos. Para cada pluralidad de antenas de transmisión, las corrientes de datos son utilizadas para producir un vector para su transmisión. Cada vector de transmisión transmitido por su antena de transmisión a través de una interfase aérea inalámbrica que experimenta una trayectoria múltiple.Los componentes de trayectoria múltiple de cada vector de transmisión transmitido, son recibidos por una pluralidad de antenas de recepción. Los componentes de trayectoria múltiple recibidos son ecualizados para recuperar los vectores de transmisión. Los datos son recuperados de los vectores de transmisión recuperados.The data is transferred in a wireless communication system, such as a dispersed spectrum wireless communication system. The data is encoded to produce a plurality of data stream. For each plurality of transmission antennas, data streams are used to produce a vector for transmission. Each transmission vector transmitted by its transmission antenna through a wireless air interface that experiences a multiple path.The multiple path components of each transmitted transmission vector are received by a plurality of reception antennas. The received multipath components are equalized to recover the transmission vectors. The data is retrieved from the recovered transmission vectors.
